Are there any actual uses of isodiaphers?
While studying atomic structure, I came across the terms isotopes, isobars, isoelectronic species, isotones and isodiaphers. While I can accept that the classification of isotopes, isobars, isoelectronic species and isotones may be useful, I do not…

Can nuclear fission or fusion occur together with bond formation in a reaction?
Is it possible for a nuclear reaction to occur simultaneously with a chemical reaction involving bond formation?
Can anyone suggest an example of this, please?

When uranium or thorium is broken down in molten salt reactors, will it produce reactive chlorine or fluorine gas?
In molten salt reactors, uranium or thorium exist as $\ce{UCl4}$ and $\ce{ThF4}$ in a 1:4 stoichiometric ratio. When a uranium is split into a barium and a krypton, the barium becomes $\ce{BaCl2}$ while the krypton is inert. As a result, two…

Fluorine isotopes and isomers
I was looking up fluorine isotopes out of curiosity. The Wikipedia entry gives info on them but adds there are also two isomers which are $\mathrm{^{18m}F}$ and $\mathrm{^{26m}F}$. What is an isomer of an atomic nucleus please someone?

How does beta decay increases the stabilization of the nuclei?
How does beta emission by a nuclei increases the general stability of it? I surely am not a specialist or anything, but this just don't make sense to me, since the objective of radiation is to release energy, but I can't figure out exactly how it's…

Why can't a reverse fission reaction be automatically classified as a nuclear fusion reaction?
$$\ce{_2^4He + _13^27Al -> _15^30P + _0^1n}$$
Will this reaction qualify as a nuclear fusion reaction? The answer to this question in the test says that it won't, yet it seems to be the reverse of a fission reaction.
Why would it not be considered…

How one calls temporal changes of chemical content due to nuclear reactions?
So, I am trying to find the term for subject question: temporal change of chemical content due to nuclear reactions. Specifically, I am interested in time evolution of the number of atoms of each isotope in, let say, spontaneous decay chain but…

Nuclear Fusion and Fission
When a heavy nucleus undergoes nuclear fission , it splits to two smaller, more stable nuclei and produces heat, similarly, when two light nuclei fuse, to make a heavier, more stable nucleus and produces energy.
The produced energy, is due to the…

How are fission products formed?
I know this question may seem a bit simple, but I would like to know about how fission products of an element are formed. There seems to be no way for krypton-92 and barium-141, the immediate fission products of U235, to decay into a fission product…

When carbon-14 decays into nitrogen-14 during β-decay, carbon-14 emits a electron while also receiving a new one. How does it add up?
As far as I understand, when $\ce{^{14}C}$ decays into $\ce{^{14}N}$, a neutron is turned into a electron and a proton, and a electron is emitted. But here is the part I don't understand.
If an electron is emitted (witch I guess means that one…

Band of stability
Here’s the band of stability as it appears in my textbook:
1- My textbook states that the last stable atom is Pb-206 and every element that has an atomic number greater than 82 is radioactive. But if every dot resembles a stable atom, why aren’t…

Why does nuclear waste contain plutonium?
According to this page on Wikipedia:
Reactor-grade plutonium (RGPu) is the isotopic grade of plutonium that is found in spent nuclear fuel after the uranium-235 primary fuel that a nuclear power reactor uses has burnt up.
Since plutonium is not…

Collison of two alpha particlesre
I was reading on nuclear chemistry - in particular, the bombardment of nuclei with alpha-particles - and was wondering what the effect of
$\ce{^4_2He + ^4_2He -> ^8_4Be}$
would be. My instinct is to recognize this as a "fusion"-like reaction, but I…

Nuclear Fusion and the worlds water supply
First off, I'm probably missing an important part of the argument regarding nuclear fusion.
What I think I know about it;
Nuclear fusion (using heat instead of gravity) is taking Deuterium and Tritium(sp?) and heating them until they fuse. This…
